So, many years ago (nearly a decade ago, wow), I wrote a future AU fanfic called Changes Are No Good, about a version of Sonic that ended up joining GUN. I made a little mix of music for said fic back in the day too. I also got an 8tracks account recently and wanted to play with it, so I recreated the mix i made on 8tracks and drew this picture to be cover art for it.
I'm still happy about how the three people in the foreground are holding guns. It shows pretty well how they feel near/at the end of the fic.
